I have a feeling this is going to make debugging code written just a few months ago incrementally difficult. At least the explicit if statements are easier to follow the intent from months ago.
This is probably going to be even less successful than the Apple watch in terms of adoption. $3.5k for a personal device -- perhaps it will capture a niche. Genre defining like the iPod or iPhone, this isn't going to be.
Using an airconditioner and lattice structures/jaali are not mutually exclusive.
As an example, if you consider large buildings like hotels that have an open central courtyard, the open spaces could use the lattice structures for cooling/circulation while the rooms, banquet/conference halls and other closed spaces can use airconditioners.
Since the lattices offer passive cooling, they can lower the overall energy bill.
Do you have a business continuity plan (for your team) that is part of the continuity plan for the overall business? If not, use this opportunity to create one. I am guessing based on my past experience that a fast moving startup may not have had time to fully plan an effective BCP (customer facting processes, technology, organization, people and process). So, doing this is generally valuable in the long run.
When you start thinking in these terms, you will be able to figure out obvious solutions that include rotating responsibilities amongst team members, how to handle inter-departmental expectations and agreements etc., Involve your team members as well so you get a full picture of all the risks and you can come up with mitigation plans (or at the least know the gaps so that you can go to your manager and have an intelligent discussion).
If you have enough time to plan this out, you can consider adding a couple of paid interns to the group to help your team members with the workload, freeing them up for taking on your tasks while you are away. Or if additional hiring is anyway planned for the future, you may be able to talk your management into advancing one or two hires sooner to help the business sail through this.
Most reasonable business managers will be able to look at things wholistically and help you find a solution that helps you and the business. There may also be resources from other departments that they may be able to borrow to help you, so don't assume anything.
Enjoy your well-deserved timeoff with your family.
